Abstract
A printing form that can be used many times has a printing surface which is provided with a metallic titanium layer. For imaging, the printing form is selectively coated hydrophilically in point-by-point manner by supplying controlled energy. After the printing, the image on the printing form can be erased by supplying heat; a method for forming images on a printing form and for erasing them; and a printing unit and a printing press including the printing form.
Claims19
A re-usable printing form having a printing surface, comprising metallic titanium in the printing surface.
A method for forming images on a re-usable printing form, which comprises a first step of providing a rewritable printing form with a printing surface having metallic titanium therein;
- a second step of creating an image on the printing surface by selectively supplying energy point-by-point;
- and a third step of erasing the image by supplying energy over a large area after a printing material has been printed.
A printing unit having at least one re-usable printing form with a printing surface, comprising metallic titanium in the printing surface.
A printing press having at least one re-usable printing form with a printing surface, comprising metallic titanium in the printing surface.
